About this job

The results

From 306hp as standard to 400hp, the BMW 335i gained 94hp, roughly 31% more power.

Torque rose from 400Nm to 600Nm (+200Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

This was a Stage 2 calibration, written for a car with supporting hardware such as intake, intercooler or exhaust upgrades. With the engine breathing more freely, the software can safely ask more of it than a Stage 1 map.

We also tuned the gearbox, raising its torque limits to match the engine and making shifts quicker and more decisive, particularly in Sport and manual modes.

How we carried it out

  • Diagnostic scan for stored faults before any work
  • Stabilised power supply connected while programming
  • Original software read and saved, so the car can be returned to standard
  • Calibration written, then the car checked again afterwards
